Power Music APP key changing & "Synchronised Page Turning"

Hi All

  1. If we load a Play List into “MY Box” from our PC. (Power Music Pro) in the correct keys we require, then download it into the iPads, we find the following.
    When we use “Synchronised Page Turning” some of the keys transfer successfully but others are incorrect. Is this function surported or am I doing something wrong.

  2. After setting up “Synchronised Page Turning” on our older iPads(iOS9) if we can then switch off the router & page turing continues OK but this does not happen on our newer iPads.

Any thoughts or help would be appreciated

Thanks & Regards
